Embodiment 1

[0033] refer to Figure 1-5 The shown one kind of heat and humidity resistant leather retanning agent polymerization reaction device comprises a base 1, a reactor body 2 arranged above the base 1 and an installation block 3 arranged inside the reactor body 2, and the upper surface of the base 1 is fixed by a fixing frame 101, the reactor body 2 is fixed above the base 1 through the fixing frame 101, and there is a gap between the reactor body 2 and the upper surface of the base 1, the inside of the reactor body 2 is hollow, and the upper end of the reactor body 2 is embedded and fixed There is a blanking base 201 that penetrates to the interior of the reactor body 2, and the installation block 3 is fixed on the lower surface of the blanking base 201. A liquid mixing device is provided inside the installation block 3, and a stirring device is provided below the installation block 3. The reactor body 2 The inner bottom is provided with a drive assembly, and the inside of the bla...

Embodiment 2

[0036] combine figure 1 , figure 2 and image 3 As shown, based on the above-mentioned embodiment 1, a mixing chamber 202 is provided above the inside of the blanking base 201, and two groups of injection pipes 203 communicated with the mixing chamber 202 are symmetrically fixed on both sides of the upper surface of the blanking base 201. The surface of the upper end is located on the rear side of the blanking base 201, and a feed pipe 204 connected to the inside of the reactor body 2 is fixed. Through the injection pipe 203, the two ingredients can be evenly introduced into the inside of the mixing chamber 202 and into the mixing hole 301. After the mixed solution inside the reactor body 2 is fully polymerized, it can be drawn out by the guide tube 204 for use.

Embodiment 3

[0038] combine figure 1 , image 3 and Figure 4 As shown, based on the above-mentioned embodiment 1 or 2, the anti-backflow component includes two groups of bottom notches 6 opened on the top wall surface of the mixing chamber 202 corresponding to the port of the injection pipe 203, and the top wall surface of the bottom notch 6 is located at the injection Both sides of the port of the tube 203 are provided with mounting holes 601 symmetrically. The top wall surface of the mounting holes 601 is fixed with telescopic rods 602 extending to the bottom notch 6. The piston 604 that is squeezed and blocked on the surface of the inner wall is equipped with a spring 603 on the outside of the telescopic rod 602, and the two ends of the spring 603 are respectively fixedly connected with the inner top wall of the installation hole 601 and the surface of the piston 604. When the ingredients are injected into 202, due to the internal pressure of the injection pipe 203, the elastic force...

Abstract

The invention relates to the technical field of polymerization reaction devices, in particular to a damp-heat-resistant leather retanning agent polymerization reaction device which comprises a base, a reaction kettle body arranged above the base and a mounting block arranged in the reaction kettle body, a fixing frame is fixed to the upper surface of the base, and the reaction kettle body is fixed to the upper portion of the base through the fixing frame. A gap exists between the reaction kettle body and the upper surface of the base, the interior of the reaction kettle body is hollow, and a discharging base body penetrating into the reaction kettle body is fixedly embedded into the upper end part of the reaction kettle body. Through cooperation of the rotating auger and the surface of the inner wall of the mixing hole, ingredients in the mixing cavity can be guided to the bottom end of the mixing hole and discharged into the reaction kettle body from the discharge port to be mixed, and in the process, the lead of the ingredients is increased through the auger, so that the ingredient mixing time is prolonged, the ingredients can be mixed more uniformly and thoroughly, and the service life of the reaction kettle is prolonged. Further, the processing quality of the polymerization reaction is improved.

Description

technical field [0001] The invention relates to the technical field of polymerization reaction devices, in particular to a polymerization reaction device for heat and humidity resistant leather retanning agents. Background technique [0002] Retanning agents can include main tanning agents, which mainly refer to leather tanning materials developed for retanning purposes, such as acrylic resin retanning agents, amino resin retanning agents and oxazolidine tanning agents, etc., according to the performance requirements of leather Choose retanning agent, such as shoe upper leather and garment leather, can obtain the desired performance through retanning with appropriate retanning agent, such as improving softness, increasing fullness, reducing part difference, enhancing water resistance, light resistance and changing leather. Surface charge, promote uniform dyeing, etc. [0003] The retanning agent is prepared by polymerization reaction. In the preparation of polymerization re...
